V7.2ZK-751W73立式双螺杆泵配YB250M-4/55KW防爆电机流量200m3/h,压力0.6Mpa输送柴油泵安装尺寸图.该泵进口口径200,出口口径200

外观形式不同,立式泵是立着的而卧式泵是横卧着. Different form appearance, vertical pump is standing and horizontal pump is lying.

连接形式不同,立式泵自下而上叠加连接,卧式泵纵向排列于底座上，立式泵通称管道泵，电机与泵体是子口连接；卧式泵是采用联轴器与电机连接，需要定期找正。 Superposition of different connection forms, the vertical pump bottom-up connection, horizontal pump vertically on the base, known as vertical pump pipeline pump, motor and pump body is seam allowance;Horizontal pump is connected by shaft coupling and motor, need to find is on a regular basis.

占地空间不同,立式泵占地面积小而卧式泵占用面积大.。立式泵组的占地比卧式泵小，不一定要打基础；卧式泵组设有底座，要打基础。 Covers an area of space is different, the vertical pump area small and horizontal pump takes up the area is large..Vertical pump group covers an area of smaller than horizontal pump, doesn't have to lay the foundation;Horizontal pump group has a base, to lay the foundation.

维修难度不同,立式泵检修难度大,如检修叶轮需将上部全部移去后方能进行;而卧式泵相对容易,如IS型泵只要将进口管移去就能进行叶轮检修. Maintenance difficulty is different, vertical pump maintenance is difficult, such as repair impeller should be the upper can all move to the rear;Horizontal pump easier, such as IS as long as the move imported tube type pump impeller repair can go.

安装形式不同,立式泵为整体连接,安装较易;而卧式泵安装后需进行精度调整. Different forms of installation, the vertical pump connection, for whole installation easier;But it's necessary for horizontal pump installed precision adjustment.

卧式泵从经济上来说比立式泵具有优势.Horizontal pump economically than the vertical pump.              

双螺杆泵有密封式和不密封式两种类型，按介质从一端还是 从两端进入啮合空间，双螺杆又被分为双吸式和单吸式两种结构。双螺杆泵是外啮合的螺杆泵，它利用相互啮合，互不接触的两根螺杆来抽送液体。双螺杆泵为一种双吸式非密闭的双螺杆泵。一端伸出泵外的主动螺杆由原动机驱动。主动螺杆与从动螺杆具有不同旋向的螺纹。螺杆与泵体紧密贴合。从动螺杆是通过同步齿轮由主动螺杆带动的。
